Phyto-synthesized nanoparticles (NPs) having reduced chemical toxicity have been focused globally and become essential component of nanotechnology recently. We prepared green phytochemically (ginger and garlic) reduced NiO-NPs to replace synthetic bactericidal and catalytic agent in textile industry. NPs were characterized using ultra-violet visible spectroscopy (UV-Vis), X-ray diffraction (XRD), X-ray photoelectron spectroscopy (XPS), Fourier-transform infrared spectroscopy (FTIR), energy-dispersive X-ray spectroscopy (EDS), scanning electron microscopy (SEM), and transmission electron microscopy (TEM). The synthesis of NPs was confirmed by XRD and UV-Vis having strong absorption at 350 nm with size ranged between 16-52 nm for ginger and 11-59 nm for garlic. Scanning and transmission electron microscopy confirmed pleomorphism with cubic- and more spherical-shaped NPs. Moreover, exact quantities of garlic and ginger extracts (1:3.6 ml) incorporated to synthesize NiO-NPs have been successfully confirmed by FTIR. Phytochemically reduced NPs by garlic presented enhanced bactericidal activity against multiple drug-resistant Staphylococcus aureus at increasing concentrations (0.5, 1.0 mg/50 μl) and also degraded methylene blue (MB) dye efficiently. Conclusively, green synthesized NiO-NPs are impending activists to resolve drug resistance as well as environment friendly catalytic agent that may be opted at industrial scale.

绿色化学合成（生姜和大蒜）还原的氧化镍纳米粒子证实具有杀菌和催化潜力。

具有降低的化学毒性的植物合成的纳米颗粒（NPs）已成为全球关注的焦点，并且最近成为纳米技术的重要组成部分。我们通过植物化学方法（姜和大蒜）制备了还原型的NiO-NPs，以代替纺织工业中的合成杀菌剂和催化剂。使用紫外可见光谱（UV-Vis），X射线衍射（XRD），X射线光电子能谱（XPS），傅里叶变换红外光谱（FTIR），能量色散X射线光谱（EDS）对NP进行表征），扫描电子显微镜（SEM）和透射电子显微镜（TEM）。通过XRD和UV-Vis证实了NP的合成，其在350nm处具有强吸收，尺寸范围在姜的16-52nm和大蒜的11-59nm之间。扫描和透射电子显微镜证实立方和更多球形NP具有多态性。此外，FTIR已成功地证实了用于合成NiO-NP的准确量的大蒜和姜提取物（1：3.6 ml）。大蒜在植物化学作用下还原的NPs在增加浓度（0.5，1.0 mg / 50μl）时对多种抗药性金黄色葡萄球菌的杀菌活性增强，并且还有效降解了亚甲基蓝（MB）染料。最终，绿色合成的NiO-NP正在成为解决分子耐药性以及可能在工业规模上选择的环保催化剂的积极分子。大蒜在植物化学作用下还原的NPs在增加浓度（0.5，1.0 mg / 50μl）时对多种抗药性金黄色葡萄球菌的杀菌活性增强，并且还有效降解了亚甲基蓝（MB）染料。最终，绿色合成的NiO-NP正在成为解决分子耐药性以及可能在工业规模上选择的环保催化剂的积极分子。大蒜在植物化学作用下还原的NPs在增加浓度（0.5，1.0 mg / 50μl）时对多种耐药性金黄色葡萄球菌的杀菌活性增强，并且还有效降解了亚甲基蓝（MB）染料。最终，绿色合成的NiO-NP正在成为解决分子耐药性以及可能在工业规模上选择的环保催化剂的积极分子。
